OPTIMIZATION OF CHROMIUM AND LEAD BIOSORPTION IN WASTEWATER USING 33 FACTORIAL DESIGN

In this study removing heavy metals, Cr (III), and Pb (II) from wastewater, Microorganism Trichoderma sp. biosorption was performed using removal taken into account. For study, 3^3 Factorial Experiment Designs were used, temperature (°C), biosorbent dosage (g/L), pH selected as the main factors for metals three levels of these determined low, medium, high. which carried out to increase metal efficiency capacity, significance each interaction examined with Design. purpose, by conducting Analysis Variance (ANOVA) via Response Surface Methodology optimization, more detailed results obtained regarding affecting wastewater.
